' tion.

My invention relates to a water lter to be used in connection 'with the regular water supply Afor filtering water for use, and the objects of my invention are: first, to improve the general form and construction of water filter for which I applied for a patent in the United States-Patent O'Hice on June 17, 1916, Serial Number 104,160, making it more efficient; second,to provide a filter of this class which will clean itself by the proper manipulation of some of the parts; third, to provide a means in connection therewith for providingy additional resistance to the water in its passage through the filter so as to give thecotton time to absorb the animal and vegetable slime in the water;

i and fourth, to provide a filter of this class which is simple and economical of construction, durable, easy to operate and will not readily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts as will be hereinafter. described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this specification in which:

Figure 1 is a side elevational view of my filter complete. Fig. 2 is a sectional view through 1 1 of Fig. 1. Fig. 3 is a perspective view of the upper resistance screen and supports. Fig. 4 is a perspective view of the gasket for holding the Yupper screen support in position and formingV a tight joint between the cap and upper end of the casing. Fig. 5 is a perspective view of one of the plunger members vand Fig. V6 is a sectional view thereof.

Similar characters of reference refer to similar parts throughout the several views.

The casing 1, cap 2, plunger members 3, resistance screen support 11,' screens 6, cloth 7, faucet 8, faucet 9 and cotton 10 constitute the principal parts of my filter.

The casing 1 is cup shaped and it is provided at its lower endv with eXtensionsla and 1b whichareprovided kwith inlet and outlet openings communicating with the inner sur- ;face'of saidfcasing for 'providing inlet yand outlet Openings thereto. Mounted in the v.outlet opening is a faucet 8. yMounted on `the open'end of Said. casing is the cap 2 which isprovided with an outlet aperture 2a into which is secured the faucet 9. Mounted in this cap 2 is the resistance screen support y 4: which is shaped as shown best in Fig. 3 of the drawings, consisting of a ring Lland another similar ring 4". Mounted between these rings 4a and 4b are a pair of different mesh screens 4d and ybetween these screens is placed a vpiece vof fine cloth 4:@ and the whole securedtogether by means of the screws 4. The 'outer edge of the ring4 4a fits into an annular recess in the ycap and against the Outer edge of this ring and against the `shoulder 2b the gasket 20 rests, its inner edge engaging with theouteredge of the ring 4b so that the gasket 2c serves as a retainer for holding thel screen supports in position and also for forming a tight, joint between the casing 1 and the cap 2. It will be here noted that the' central holes in the rings 4 and 1b are small so as to retard the fiow of water giving the cotton a chance to absorb the slime from the water in its course through said cotton. Mounted in each end of the casing are the plungers 3 which consist of a ring 3a, another ring 3b which is provided with a plurality of lugs 3? adapted to prevent the plungers from tilting in the casing and to provide a space on the outer sides of said plungers. Mounted between the rings 3a and 3b are a pair 0f different mesh screens .6 and mounted between the screens is a piece of fine cloth 7 andthe two rings 3a and 3b are secured together by means of the screws 3d. Mounted between the two plungers in the casing 1 is a mass of cotton preferably cotton waste. The extension 1a is adapted to connect with the regular service pipe as it is threaded externally with a regular pipe thread for that purpose. If it is desired to filter the water the faucet 8 is closed and the faucet 9 opened and the water passes through the screens and cloth in the lower plunger through the cotton waste 10, through the screens and cloth in the upper plunger then through the screens and cloth over the smaller hole in the resistance screenmorecompact the cotton becomes and the more efficient the filter. The small holes Y through the rings La and 4b with the screens and cloth covering the same form a resistance for holding the water back and give the cotton time to absorb the animal andvegetable sli-me in its passage through the cotton and also serves as an additional means of filtering' the water just before its passage for use. In cases where it is not desirable to filter the water the faucet 9 is closed and the faucet 8 opened and the water passes through the lowerend of the filter carrying withv it the coarse dirt which will not pass through the first screens and cloth when filtering thus cleaning the coarse dirt from the filter, also the slime and finer dirt carried upward into the cotton and other screens may be cleaned from the filter by opening the faucet 8 wide open and opening the faucet 9 slightly and allowing the water to pass out of the faucet 8 will cause a backward pressure which will cleanse the filter of dirt and slime.

Though I have shown and described a particular construction, combination and arrangement of parts, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the purview of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: Y

l. In a filter of the class described, the combination of a casing provided with an inlet port and an outlet port at its lower end, a plunger in each end each provided with screens and a cloth placed between said screens, co-tton placed between said plungers, a cap secured on the upper end of said casing, an outlet faucet communicating with the inner surface of said cap, and a resistance means between the upper plunger and said cap comprising two ring supports with small sized apertures therein and screens secured between said ring supports.

2. In a filter of the class described, the` combination of a casing provided with an inlet and outlet portat its lower end, another outlet port at its upper Lend, a pair of plungers reciprocally mounted therein each carrying screens with a cloth placed between the same, a mass ofk cotton placed between said plungers in said casing, and a resistance member secured in the upper end of said casing comprising rings with small pcrforations therein, screens secured between said rings and a cloth secured between saidscreens.

In testimony whereof, I have hereunto set my vhand at San Diego,California this 25th day of October, 1916.
